Screen Machine portable, trackmounted impact, cone and jaw crushing plants are hard at work with all varieties of rock crusher operations, aggregate producers, recycle concrete and asphalt, bricks and more.
Jaw crushers are heavy duty machines and hence need to be robustly constructed. The outer frame is generally made of cast iron or steel. The jaws themselves are usually constructed from cast steel. They are fitted with replaceable liners which are made of manganese steel, or Nihard (a NiCr alloyed cast iron).
